GAS-RETORT-DISCHARGING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 447,022, dated February 24, 1891 Application filed March 6, 1890. Serial No. 342.870. (N0 model.)

To all whom, it may concern:

Be it known that I, GASTON A. BRONDER, of New York, in the county and State of New York, have invented a certain new and useful Improvement in Gas-Retort-Discharging Apparatus, of which the followingis a specication.

My improvement relates to apparatus by which coke and residual products remaining in gas-retorts after the destructive distillation of coal therein has been completed may be removed.

I will describe an apparatus embodying my improvement in detail, and then pointoutthe novel features in claims.

In the accompanying drawings, Figure 1 is a side elevation of apparatus embodying my IIDPI'OVGIDQHE and showing three retorts in vertical section. Fig. 2 is a side view, on an enlarged scale, of one of a number of rakes Fig. 3 is a top view of the same. Fig. 4 is a view on a larger scale of one of the rake-heads, looking from the inside of the same. Fig. 5 is a View on a scale similar to Fig. 4 of another of the rake-heads, looking from the outside of the same. Fig. 6 is a detail end view, on substantially the same scale as Figs. 4 and 5, of guides for the rakes. Fig. 7 is a view on a similar scale looking from the side. I

Similar letters of reference designate corresponding parts in all the figures.

A designates a truck supported upon wheels (L, which travel upon tracks at, extending along in frontof a bank of retorts B. The truck may be moved along into any desired position infront of the retorts. The truck comprises a base-piece A, upright-s A A 1, extending fronrthe base A at the ends of the truck, and connecting-bars a extending between the end uprights A A The upper of the cross-bars a constitute rails upon which a carriage O is supported and guided and upon which said carriage may be moved along. I have shown a brace-rod a at the upper art of the truck, connecting the 'uprights'A The carriage C comprises a frame 0, upon which are mounted wheels 0, which travel upon the rails a Secured to one side of the frame 0 is an upright 0 extending from the inner sides of which are pins or projections c Extending from one side of the rear upright A are pins or projections 0.

At the forward end of the truck is a sliderbar D, adapted to be moved vertically in guideways 01 upon the forward upright A Secured upon the slider-bar D are pairs of rollers (1. (Shown more clearlyin Figs. 6 and 7 These rollers are loosely mounted upon stub-shafts d which are secured in the sliderbar D. The slider-bar D at points intermediate of the rollers d is provided with inwardly-extending projections d Hung upon the upper of the stub-shafts (l in g device D. Each of these retaining devices near its lower end is provided with a notch 01*. The retaining devices may be swung into such position that the notches (I will embrace the lower of the stub-shafts d of each pair outside the lower roller d. It may be locked in such position by a nut (1 upon the screw-threaded outer end of the stubshaft d About midway in its length each of said securing devices is provided upon its inner side with a projection d, which, when the retaining device is swung downwardly into the position just described, will be opposite the projection 01 upon theslider-bar D. The rollers d and the projections d act as guides to prevent vertical or lateral displacement of rakes E E, which pass between them.

I have shown three pairs of the rakes EE; but I may use any desired number. These pairs of rakes are each adapt-ed to be moved forward and backward, either separately or together, by the carriage 0 when the latter is moved by any suitable means. (Not shown in the drawings.) The rake E of each pair is mounted upon its complementary rake E, and is capable of being longitudinally moved thereon, so as to lengthen or contract the length of the rake as a whole. Each pair of rakes therefore constitutes in effect an extensible and contractible rake. It has been found advantageous to make the rake thus extensible and contractible in order that a longer rake having a greater reach into the retorts may be used within a limited space than would otherwise be possible. The handies of each of the rakes is'made of comparativelynarrow metallic bars. The rakes E are provided with heads 6, shown as' of substantially oval shape. The rakes E are provided with substantially oval-shaped heads e with each pair of rollers is a swinging retain- The handles of the rakes EeXtend through suitable apertures e formed in the head 6 of the rakes E and are provided with upwardly-extcnding projections c, which preventa too-extended forward movement of the rakes E upon the rakes E.

Upon the rear ends of the rakes E are pivoted swinging arms F, which may be swung around into line with the handles of the rakes or into posit-ion at right angles thereto, as shown at Figs. 2 and 3. WVhen the rakes E have been moved into their most forward position on the rakes E, the armsFare swung around into line with the handles of the rakes, and should the rakes be connected to the carriage C, so as to move therewith, projections f, with which the upper sides of the arms are provided, will contact with projectionsf, extending from the frame 0 of the carriage O, and will thus prevent rearward longitudinal movement of the rakes E upon the rakes E. Thus when the rakes have been extended the heads 0 6 will be maintained in proper position relatively to each other. Each of therakes E is provided nearits rear end and upon its under side with a notch 6 These notches are adapted to be passed over the pins or projections 0 upon the upright a of the carriage C when it is desired to secure the rakes to the carriage, so that they will bemoved thereby. When it is not desired to move the rakes with the carriage, they are lifted off from the pins 0 and are engaged with the pins 0 upon the uprights A Extending from the sides of the rakes E are pins or projections 6 which, when the rakes are engaged with the carriage, will contact with the upright c and act as stops to prevent independent forward movement being imparted to the rakes E E while in operation, or, in other words, which will cause the rakes to be drawn rearwardly by the carriage during this rearward movement.

It being desired to operate one or more of the extensible rakes, the rake or rakes E are moved forward into their farthest position upon the rake or rakes E. The latter are then secured to the carriage as desired, the arms F being swung around into line with the rakes E. The carriage is then moved forward, so as to carry the rakes into the retorts. Vhen the rake-h eads e e have reached the rear of the retorts, they will drop downwardly at or near the rear of the material therein, and the returning movement of the carriage will cause a portion of. such material to be raked from the retorts. Such material as is not raked out by the head 6 will be raked out by the head 6, and a few toand-fro movements of the carriage U will suffice to thoroughly empty the retorts.

The vertical movement of the rakes which is necessary to permit them to pass over the top of the charge in the forward movement and to drop down behind the charge previous to the return is effected by the movement of the s1ider-bar D in the ways (Z. This movement is produced in the usual manner. The weight of the slider-bar and the rakes is counterbalanced by a weight 9 upon a lever 9,

connected by means of a link g to the upper end of the slider-bar.

In Fig. 1 I have shown in dotted lines the position which the rollers (1 may occupy when in a lowered position. The rakes may be easily placed upon or removed from the truck by swinging the retaining devices 1) around sufficiently to admit of this.

What I claim as my invention, and desire to secure by Letters Patent, is

1.. In apparatus for discharging gas-retorts, the combination, with a track, of a carriage mounted on the track and an extensible and contractible rake havingaremovable engagement with the carriage for moving it forward and backward with the carriage or not, at pleasure, substantially as set forth.

2. In apparatus for discharging gas-retorts, the combination, with a track, of a carriage mounted on the track and an extensible and contractible rake composed of two parts, each provided with a rake-head, one of the parts having a longitudinally-sliding engagement with the other part, said parts being controlled in their movements by the movement of the carriage, substantially as set forth.

In apparatus for discharging gas-retorts, the combination, with a track, of a carriage mounted on the track, an extensible and contractible rake composed of two rake-sections, one of the sections having a longitudinallysliding movement upon the other section, the rake having a removable connection with the carriage, and stops located in position to engage one of the rake-sections and limit its longitudinal movement relatively to the other section, substantially as set forth.

4. In apparatus for discharging gas-retorts, the combination, with a track, of a carriage mounted thereon, an extensible and contractible rake having a removable connection with the carriage and consisting of two rake-sections, one of the sections having alimited longitudinally-sliding movement relatively to the other section, and a swinging arm upon one of the rake-sections for causing itto be slid upon the other section, substantially as set forth.

5. In apparatus for discharging gas-retorts, the combination, with a track and a carriage mounted thereon, of a reciprocating rake under the control of the carriage and a guide for directing the rake, said guide consisting of a pair of rollers in position to engage the opposite sides of the rake-handles, a permanent guide-barin position to prevent the rake from displacement at one side between the rollers, a swinging bar having a movement into and out of position to keep the rake from displacement at the opposite side between the rollers, and means for locking the swinging bar in position, substantially as set forth.
